The ERRATA_SME_POWER_DOWN flag doesn't account for the recommended state
ID encoding, only for the default one. This patch makes it work by
removing the generic flag and incorporating the functionality into the
CPU and platform layers.
The ERRATA_SME_POWER_DOWN is an awkward fix in generic code to a
platform problem. The PSCI layer shouldn't care about any CPU's inner
workings but it does. This isn't ideal once the issue is fixed since
we'll have to carry the "legacy" fix in generic code.
This patch is marked as breaking since the ERRATA_SME_POWER_DOWN flag is
removed and a couple of lines are required if CPU hotplug encounters a
powerdown with live SME state (CPU suspend will work as before). This
will get discovered with a panic at EL3 so this patch leaves a comment
to be able to trace it back.
